SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

Generates component-level unit tests from source files and, optionally, a scenario-set to map scenarios to test cases, while avoiding overwriting existing tests and aligning with the project’s testing strategy.

Core Features & Use Cases

  • Framework-aware test generation for Vitest or Jest using repo fingerprints; detects the correct framework without guessing.
  • Enforces a strict Arrange-Act-Assert structure in every generated test and preserves every scenario as a separate test case.
  • Supports on-demand invocation and PIPELINE-1 step integration, coordinating with test-strategy planning and contract/test-writer workflows.

Quick Start

Invoke /vibeflow:component-test-writer <path-or-glob> to generate tests for the specified source files.

Frequently Asked Questions about component-test-writer

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I generate unit tests for Vitest or Jest without manually configuring the framework?▼

Generate unit tests by pointing the tool at your source files; it uses the repository fingerprint to detect whether Vitest or Jest is configured and produces framework-aligned test code automatically.

How do I generate component tests that map directly to my test scenarios?▼

Provide a scenario-set.md file alongside your source files; the generator maps each scenario to a separate test case, preserving every scenario as an explicit Arrange-Act-Assert structured test.

Can I generate unit tests without overwriting my existing test files?▼

Yes, the component test generator explicitly avoids overwriting existing tests, reading your current test suite and only adding new test cases while logging all decisions to a run log for traceability.

What is the best way to enforce Arrange-Act-Assert structure in automated unit test generation?▼

Use a test generation tool that enforces an explicit Arrange-Act-Assert structure per test case, ensuring deterministic results and strict separation of test setup, execution, and assertion phases.

Do I need a scenario-set file to generate component-level unit tests?▼

A scenario-set is required to map scenarios to test cases, but the tool reads scenario-set.md when present and can still generate component tests from source files while aligning with your testing strategy.

Why do my generated unit tests need a run log for traceability?▼

A run log provides traceability by recording the test generation decisions, including framework detection via repository fingerprints and scenario-to-test-case mapping, ensuring deterministic and auditable test outputs.
